Health physicists are professionals who specialize in radiation safety and protection. They work to ensure that people, the environment, and equipment are safe from harmful effects of radiation. This includes monitoring radiation levels, developing safety protocols, and educating others about safe practices in settings like hospitals, research facilities, and nuclear power plants. These experts often collaborate with other professionals, such as medical physicists and radiologists, to assess and manage radiation exposure. They play a crucial role in regulatory compliance, helping organizations adhere to guidelines set by agencies like the Nuclear Regulatory Commission and the Environmental Protection Agency.
